The Kicker TRTP102 down-firing 10" CompRT subwoofer enclosure in an upgrade and improvement on one of the best loaded enclosures available. This 10" CompRT loaded box comes with a passive radiator to give you the increased output you get from a ported box, but without the port noise and without the extra space needed for a ported enclosure. This box is truly amazing. You can mount it nearly anywhere. It can fit under the rear seat of a truck, you can put it behind the seat in a single cab truck and face it backwards, and if you put it in the trunk, you have a ton of different mounting options which do not eat up all of your storage room.
From a sound and output perspective, you are not sacrificing anything. For the money, this might be the best loaded enclosure on the market. The bass response is tight and accurate.
